@Gargron yeah see I'd call this a castle but it's close to the boundary. Maybe my decision criteria is wrong. I basically think turrets + rugged location = castle. Ramparts are an even surer sign. (getting dangerously close to "featherless biped" territory here)

Reading English wikipedia it seems like a palace is a luxuriant dwelling. while a castle is built to be defended. So I guess Neuschwanstein is technically a palace though it has been built in a Romantic style to look like a castle!

@Gargron @tomharris I *think* it's about how they're used with a Schloss being something aristocrats live in and a Burg being more like something used for protection.

The terms also seem to be used somewhat interchangeably in german tho so people will know what you mean either way.
